To all whom 'it may concern;

i Be it known that I, ELMER L. LINXWLILER, a citizen of they United States, the county of Archuleta, near the town of Allison, State of Colorado, have invented new and useful Improvementsin Irrigating- Conduits, of which the following is a 'speci- My invention relates to new' and useful improvements in irrigatin conduits.

The principal object o my invention is to provide a cheap, simple and eifective means for distributing'irrigating Water, and is more particularly adapted to the furrow system of irrigation. v

The great diliioulty experienced in irrigating systems, of preventing an oversupply of water from washing land out of a furrow and depositing large quantities of silt therein, demands a: system which will more evenly apportion the water to the furrows and prevent the deposit ofsilt in the same.I A

system of irrigation which will uniformlydistribute the water to each furrow by night with equal accuracy and faithfulness as by day, is also desired, as irrigation by night is more effective than by day due to-the influence of the suns vrays on the evaporation of the water.

lVith a View of meeting the above requirements, as well as others which will hereinafter be specified, my invention is designed, and consists of a light, liexible conduit of tapering form for dii-itributingr the irrigation water through apertures therein, to the several furrows. These apertures are spaced at suitable' distances apart, and' are respectively protected from wear and enlargement by devices to be hereinafter described, which also serve to regulate the How of water through said apertures. The extreme flexibility of my conduit enables it to be easily carried from one place to another and to accommodate itself to uneven surfaces suoli as slopes, gulleys, etc., while its tapering quality insures a `uniform flow of water through the apertures before referred to. This even diflitributioii of the wateris of great value to the crops in providing a uniform growth as opposed to methods which put too much water in some placesand not enough in others.

With the above and other incidental objects in view, my invention consists in the certain novei arrangement and construction of parte to .be hereinafter described in the Speciioation of Letters -Patent.

apertures, as well as protecting the latter from wear and enlargement. Fig. 3 is a section onv the line a-a'of Fig. 2', showing my regulating and protecting device inrposition over an aperture of the conduit. Fig. v line b-b of Fig. 2, showing themethod of clenching my regulating and protecting device to the conduit. Fig. 5 is a plan view of the slide for opening and closing the aperture of the regulating and protecting device. Fig. 6 is an end View of thelsaine, showing the lip for moving the slide. -And Fig. 7 is a side view of the clamp for closing the conduit.

Throughout the specification and drawings, like reference characters denote corresponding parts.

In a detailed description of my 1 designates a iiexible conduit or hose made of canvas or other suitable iexible material, and tapering throughout its length. The large end of the conduit l is provided with an externally screw-threaded: steel coupling 2, Wherebythe said conduit may be connected to a pipe or fiume for the lpurpose of reinvention,

ceiving irrigating water therefrom. The

other-end of the conduit 2 is provided with an internally screw-threaded steel coupling 3 adapted to receive another sect-ion of a similarly constructed conduit when an increase in length is desired. Provided in the conduit 1, at suitable distances apart, `ire apertures ll, preferably of the form 4of wn oblong rectangle, each aperture being adapted to deliver water directly to a furrow. Tn order to insure a uniform flow of water through the apertures 4e, my conduit is made of tapering form, since in a cylindrical'conduit the water would diminish in volume as it iows along, thereby delivering too much water to some furrows vand not enough vto others, as Well as depositing silt in shallow places.

For the purpose of protecting the apar# tures 4 from wear and enlargement, as well as providing means for Aregulating the How of water therethrough, I provide an apertured plate 5 which is adapted to be fitted over each aperture. This late is made of thin metal, is preferably of the fornrof' an oblong rectangle, and is constructed as follows: Referring to Fig. 2, 5 represents the metallic plate in which is' provided an aperture y6 of suiiicient size and shape to .register with an aperture 4 of the conduit 1. The aperture 6 is formed in the plate 5 in such a manner as to provide four flap portions 7. When the plate 5 is applied to the conduit 1 so `"that the apertures 6 and 4 register with eachother, the [lap portions 7 are first bent down through the aperture 4 and then back vupon the interior` surface of the conduit,

whereby' they serve not only as means for clamping the plate to the hose, but also as means for protecting the edges of the apertures- 4 from enlargement and wear, see Fig. 3.. The apertured plate 5 is also scored and cut to form 12 tongue-like projections 8, three on each side, to form means for clenching th'e plate to the conduit in the following manner: When the plate 5 is applied to the conduit 1 in the manner before stated, these projections-8 are forced through the said conduit and then bent down uponits inner surface, as is shown. in Fig. 4, whereby the plate and conduity are firmly united. The projections 8 are so cut or stamped from the plate 5 as to leave between them longitudinal llap portions 9. These flap portions!) are eight in number, the two formed on the upper side of the plate being similar to the two formed -on the lower, and' the two formed on one end of. said plate are vsimilar to the two formed on the other end. The upper and lower flap ,portions 9 form guiding and retaining means for a slide 10, which-is longitudinally movable therein lto open and close the aperture 6 of the plate 5, see `Figs.- 2, 3 and 5.' The slide 10 is provided atv one end with a lip 11 adapted' to be gripped by the hand ofA a person adjusting the slide. While I have shown a curved lip for this purpose, any other suitable gripping medium may be employed. By adjusting the slide 10 with reference to the aperture 6, the quantity of water flowing through said aperture from the flexible conduit 1 may be regulated to suit varying conditions of use.

Referring to Fig.' 7, 12 designates a clamp adapted to be fitted over the conduit 1 to close any portion of the same. "Ihe said conduit, being open at both ends, may be cleaned at any time, and when it is desired -to .close the lower end, or any .otherportion' of thesame, the saidclamp is applied to the j conduit at the particular" place it is desired to close it. For example, if a short length of hose is desired, the said conduit 1, being flexible, may be bent upon itself and the clamp applied at its middleportion, whereupon the irrigating water will flow only through those apertures which are located between the large end of the conduit and the clamp. lVhile any suitable clamp may be employed, the one herein shown is constructed as follows: Into a transverse member 13 are fitted two screw-threaded bolts 14. These bolts 14 are adapted to receive a transverse member l5, vertically adjustable thereon, and also handles 16 to move said member 15 into engagement with the conduit 1k and thereby close the same at any desired point.

In order to add to the imperviousness and durability of the conduit 1, it may be treated with a water-proofing or preservative fluid;

In operation, the `water admitted to the conduit 1 from the irrigation pipe or fiume (not shown), will flow through said conduit l to the place where the clamp 12 is'applied,

and will be distributed, through the apertures 4 betweenA the end of the conduit and I the clamp, to the furrows of a field or orchard. The amount of water flowing through the apertures 4 may be controlledby adjusting the slide 10 in the apertured plate 5'. in'g, in connection with the further fact that the amount ofwater flowing through each aperture may be regulated, makes 'it possible to provide for a very minute flow into each furrow, as wellras a uniform flow.

My invention is not limited to the details of 'construction and arrangement herein shown and described, but the character of the means employed may be varied to suit different conditions of use.

Having described my invention, I.- claim:

A flexible irrigating conduit for distributing water into furrows, apertures in said conduit spaced apart at suitable distances to communicate with the furrows, and one for each furrow, a plate itted over each aperture and provided with an opening registering with. said aperture, tongues projecting lfrom said plate, said tongues extending through the down upon the interior surface of the conduit to secure the plate to said conduit, and a slide movable in said plate to open and close the opening in the plate -to regulate the flow of water therethrough, said conduit tapering throughoutiits length to insure an even distribution of waterV through said apertures, substantially as described.

In testimony whereof I have hereunto set my hand this 6th day of April, 1912.
